What do I need do to solve this error?

Assuming you already checked the construction as recommended in the EnergyPlus output "Check the solar absorptance of the inside layer of the floor surface construction/material" make sure the surface type is set to "Floor" for one or more surfaces in the affected zones.

Severe * DetermineShadowingCombinations: There are 1 surfaces which are casting surfaces and are non-convex. * ~~~ * ...Shadowing values may be inaccurate. Check .shd report file for more surface shading details * ~~~ ** ...Add Output:Diagnostics,DisplayExtraWarnings; to see individual severes for each surface. any idea for this?

This has nothing to do with your original question. Non convex surfaces have been extensively discussed already... please use the search function. (see here for example)
